The Adams Radial Tank (officially the 415 class, later O415 when put on the duplicate list) have a somewhat complex history. They were built by 4 different manufacturers -              
       Beyer Peacock - 12 built 1882, 1000 gallon tanks, 36" trailing wheels, frame pattern 1            
       Stephenson -       18 built 1883, 1000 gallon tanks, 36" trailing wheels, frame pattern 1            
                                  10 built 1885, 1200 gallon tanks, 42" trailing wheels, frame pattern 1            
       Neilson -             11 built 1885, 1200 gallon tanks, 36" trailing wheels, frame pattern 2            
       Dubs -                10 built 1884, 1200 gallon tanks, 36" trailing wheels, frame pattern 1            
                                 10 built 1885, 1200 gallon tanks, 42" trailing wheels, frame pattern 1, round spectacles                   
Frame patterns (front end)     1         small ogee at cylinder end, angled straight to buffer beam
                                                2         large ogee at cylinder end, horizontal from final curve to buffer beam
                                                some rebuilds        as for 1, but simple curve instead of ogee        
             
Note - all wheels have rectangular section spokes except for Dubs who used oval section spokes for bogie and trailing wheels.             
             
Note that 488 as preserved has ended up with the incorrect oval spokes on the bogie wheels - this seems to have happened  when the loco was restored for preservation. It also acquired strange wooden spectacle frames at this time.             
             
All but 2 of these locos were withdrawn between 1921 and 1928. 125 and 520 were retained to work the Lyme Regis branch - other locos being too heavy. 488 had already been sold to the Government in 1917. In 1919 it went to the East Kent Railway.             
SR bought 488 back in late 1947 and reboilered it with a Drummond boiler. As BR was formed on 01/01/48 it is possible (but not certain) that it never appeared in Southern colours.             
             
Drummond hated stove-pipe chimneys (and often seemed to move to Railways using them!) so he replaced the Adams chimneys  with his own design. He also replaced some of the boilers with ones where the safety valve was moved to the top of the dome.             
Some locos were fitted with double slide bars and crossheads in place of the Adams single bar design.             
He also fitted coal rails to the bunker and some engines had motor train gear on the cab roof.             
             
The result of all this is that there is no real substitute for photos of the loco you are modeling!
